Hi Riamus2

Thanks for your advice.

Actually I have been using MIRC program for sometime. So far, Mcafee scans doesn't show this problem till this morning and I check at mcafee website, it was detected two months back and just place it in its dat engine recently. I was just worried it might be a back door program for trojan.

Generic pup.j was found in 3 files, ie 2 files in c:\programe files\mirc\mirc.exe and 1 file in c:\system volume information\_restore

Should I just leave it alone?

Appreciate for your help.
